If a 9600 bps modem is not available, a slower modem can be used with the debug kernel. If the modem supports "speed conversion" (a 2400 bps modem with error-correction and compression will support speed conversion), setup is straightforward. Construct the proper initialisation string for the modem, making sure that the modem's DTE speed (modem-to-debugger) speed is locked at 9600 bps. If the modem does not support "speed conversion," construct an initialisation string for the modem, and create a KDB.INI file that resets the debugger to the speed supported by the modem. For example, .B 2400t 2 for a 2400 bps modem. In this case, the person calling the debugger will have to use the speed supported by the modem.
